Quae in libro meo 1847 et 1848 edito „Mono- 
graphia Heliceorum viventium" de methodo et ratione 
scribendi praefatus sum, ea hic repetere non in animo 
cst. Terminologia adoptata, methodus metiendi testas, 
etc. omnino eadem sunt ac in illo hbro, et pariter omnes 
species, quas non ipse vidi et descripsi, eodem signo 
„•}•" distinxi. 

DifFerentia autem gravis in methodo systematica 
apparebit. In famiha Hehceorum pauca admisi genera, 
testae solum structura vix sufficienter definita; in ordine 
Pneumonopomorum , charactere essentiah, ilh Pneumo- 
nobranchiorum famihae deficiente, operculo orga- 
nico scil. praedito, methodum recentiorum Auctorum 
secutus, genera ex opercuh substantia et conformatione, 
una cum testae ipsius characteribus cu'cumscripta admisi. 
Naturae congruum mihi non videtur, si complectimur 
in uno eodemque genere animaha, quae construunt 
operculum Cyclostomatis volvuli et elegantis, vel (ut de 
Lamarckianis modo speciebus loquar) Cycl. mammillaris 
et lincinellae. Genus Pupina, adoptatum a plerisque 
Auctoribus, qui genus Cyclostoma in sensu Lamarckiano 
servant, difficihus a Megalomastomate generice separari 
potest, quam Cycl. flavula a C. obsoleta Lam. 



VI PRAEFATIO. 

At vero gravis determinandi species Cyclostoma- 
ceorum difficultas eo exoritur, quod saepe testae in 
collectionibus servantur vel novae afferuntur operculo 
destitutae , quare , ut evitarem in ipso libro methodum 
minime scientificam, quam in Monographia Hehceorum 
adoptare coactus fui, clavem praemisi analyticam om- 
nium specierum in hbro descriptarum , in qua opercuh 
nuUa fit mentio. Sic comparatis externis testae charac- 
teribus loci facile erui possunt, quibus singula testa in 
Monographia quaerenda est. Quamvis recentiorum col- 
lectorum studiis longe maxima pars specierum cognita- 
rum locum fixum in systemate obtineat, multae tamen 
restant, quae solum ex analogia testarum uni vel alteri 
generi attributae sunt, Muha, quae in primo ejusmodi 
conatu (in Zeitschr. f. Malak. 1847. p 104) erronea 
fuerunt, temporis progressu jam correcta et emendata 
sunt, et quae ex deficiente opercuh cognitione dubia 
mihi restant, suo loco exacte indicata sunt. 

Numerus specierum huc pertinentium indiem ac- 
crescit, et multae, quae antea rarissimae fuerunt, nunc 
in omniuni inanibus versantur, quare sperandum est, 
historiam Pneumonopomorum, junctis viribus et studiis, 
mox ad iham exactitudinem perventuram esse, qua 
cognitio aharum famiharum, praesertim ex Ctenobran. 
chiis, jam gaudet. 

Quae in hbro, Tibi, Benevole lector, nunc exhibito 
emendanda et addenda erunt, Deo favente postea in 
Supplemento proponentur.

MONOGRAPHIA 

PNEUMONOPOMORUM VIVENTIUM 



Introdiictio. 

Pneumonopoma sive Pneumopoma dicuntur Mollusca 
terrestria aerem per organa pulmonibus analoga spirantia et 
operculo organico, pedi animalis affixo, pede retracto testam 
spiralem claudente, munita. 

Animalia hujus ordinis omnia structura valde simili gau- 
dent, qua praeter operculum facile a reliquis molluscis ter- 
restribus (Limaceis, Heliceis, Auriculaceis veris) distinguuntur. 
Sunt nempe sexus distincti (nec unquam Hermaphrodita, sicut 
Helicea), et tentaculis 2 contractilibus (non retractilibus) prae- 
dita, ad quorum basin posticam vel externam ocuH positi 
sunt. Pallium in nonnullis margine Ubero praeditum est (quo 
signo Cl. F^russac famiUam HeUcinarum a Turbicinis distinxit), 
in aUis testa omnino absconditum. 

Ordo MoUuscorum, quem hic tractaturi sumus, primum 
a Cl. Ferussac 1821 (Tabl. syst. p. XXXHI.) tamquam 
quintus Gasteropodorum ordo sub nomine Pulmovatornm 
operculatorum propositus est ad conjungenda duo genera : 
Cyclostoma et Helicinam , quorum intima affinitas naturaUs 
a praecedentibus auctoribus, immo Cl. Cuvier etLamarck 
plane neglecta fuerat. Utrumque hocce genus Ferussacio 
typum propriae famiUae : Helicinarum et Turhicinarum sistit. 

Cl. Latreille 1825 (Fam. nat. Ed. germ. p. 176.) 
primum ordinem Gasteropodorum dioicorum nomine Pneumo- 
pomorum designavit, quem, simiUter ac F^russac, in fami- 
Ham Helicinidarum et Turbicinorum divisit. 

Idem ordo Cl. Menkeo 1828 (Syn. p. 22.) sextus 
Gasteropodorum est, nomine Coelopneumonatorum opercula- 
torum designatus, et in famiUas Helicina<forurn et Cyclosto- 
miatarum divisus. In altera ejusdem operis editione (1830. 
p. 39) nomina: Coelopnoa operculafa et, pro famiUis, Heli- 
cinacea et Cyclostumacea prioribus substituta sunt.

2 INTRODUCTIO. 

Cl. Deshayes 1830 (Encycl. m^th. III. p. 552. Tabl) 
designationem UeUchieorum (Les Helicines) pro tertia Pul- 
mobranchiatorum lamiha, genera: Cyclostoma, Strophostoma 
et Helicinam complectente, proposuit. 

Cl. Wiegmann 1832 (Handb. d. ZooL p. 527. Ed. 
sec. p. 555.) ordinem nostrum tamquam famiham Puhiiona- 
torum nomine abbreviato Operculatorum tractavit , genera ei 
adscribens: Cyclostoma, Helicinam, Steganotomam et Pu- 
pinam. 

Cl. Anton 1839 (Verzeichn. p. XIII. 52.) nomine Cy- 
clostomaceorum famiham designat, praeter Cyclostoma et 
Helicinam etiam Littorinam minus bene complectentem. 

CL Hartmann 1840 (Erd- u. Siissw. Gast. Syst. 
Uebers.) nom. Pseudobranchiatorum seu Teleoyeophilorum 
genei*a Choristoma, Pomatiatem et Cyiiostoma conjunxit, 
cui sectioni Helicina certe adscripta fuisset, si generum non 
in Europa obviorum mentio facta esset. 

Sectio Pneumonohranchiatorum operculatorum a CL 
Gray 1840 (in Turt. Man. Ed. sec. p. 273) proposita, etiam 
nostro ordini congrua est, etsi illo loco sokim familia Cyclo- 
stomidarum tractata sit. 

CL D'Orbigny 1841 (Moh. Cub. I. p. 199. 236.) in 
prima famiha Pectinibranchiatorum dioicorum Cyclostomidas 
admittit, cui genera: Odontostoma (ad Hehcea potius refe- 
rendum), Helicina, Cyclostoma et Strophostoma subjunguntnr. 

CL Reeve 1842 (Conch. syst. II. p. 90.) wommQ Cyclo- 
stoniaceorum eundem ordinem designavit, admittens inter ejus 
genera praeter Pupinam., Cyc/ostoma et Helicinain etiam 
Truncaiel/am, ; quam methodum secuta est CL A. Catlow 
1845. (Conch. Nom. p. 168.) 

CL Sismonda 1842 (Syn. an. inv. p. 27.) nomine 
Cyc/ostomatum , tamquam Gasteropodorum sectionis, Cyclo- 
stoma et Helicinam complectitur. 

CL Jay 1850 (CataL of Shells p. 251.) familiam C^/c/o- 
stomaceorum statuit, cujus genera sunt: Pupina , Trunca- 
fe/Ia, Cyclostoma, Geomelania, Uelicina, Stoastoma. 



Dividendus videtur ordo Pneumonopomorum ex animahum 
structura externa , nempe positione oculorum , in subordines 
duos : Opisophthalma (Auriculaceis affinia) et Ectophthalma.

Haec familia auctoribus diu pro unico genere Cyclosto-

eorumque operculorum cognitione necessitas constiterit , ab 
initio pauca, sensim plura genera ab eo separandi, quae suo 
loco enumerabuntur vel inter synonyma citanda erunt. 

Sicut 1851 in Conspectu emendato generum et specierum 
Cyclostomaceorum (p. 3. Conf. Zeitschr. f. Mal. 1851. p. 131.) 
exposui, ex formatione operculorum tres series generum pri- 
marie distingui possunt, et quaevis series iterum ex opercu- 
lorum substantia et testarum characteribus varios ty|5os gene- 
rum mao;is minusve exacte definiendorum offert.

Series secunda. Operculum subcirculare, anfractibus 
paucis, sensim accrescentibus, nucleo subcentraU. 

I. Opercukim testaceum. Genera: Jamaicia, Licina?. 
Choanopoma. 

II. Operculum cartilagineum. Genus : Adamsiella. 
Series tertia. Opercukim ovale vel angulatura, an- 

tractibus paucis, magis minusve celeriter accrescentibus, nucleo 
excenuico.

difforme. Elle est elargie a sa base, pointue au sommct, formee de six 
tours arrondis, surbaisses et turricules, couverts de stries longitudinales tres 
fines ; ces tours sont separes par une suture lineaire et enfonce'e. Le der- 
nier est beaucoup plus grand que tous les autres, plus large (|ue haut ; il

**) This may bo a variety of C- variab/Ic; it is chicfly distinguished 
by having the hxmellae between the iuner and outer peritremes so much 
produced as to appear like numerous concentric margins ; by having the lip 
reflected farther back ; by a more slender general forni , the niean diverg- 
ence being 33" to 35". The lip is reddish purple, witli darker rays of thc 
same conspicnous in the more siniple lip of the young , and the square 
sutural spots are ahvays faint. (Adams 1. c.) 

***) Shell ovate-conic, moderatcly clongate; reddish brown with a series 
of rather dark spots of the sanie; vvith very thin and sharj} transverse pei'-

about three whorls ; remaining whorls four and one half, moderately convex,

Mean divergence about 40"; length 0,57, greatest breadth 0,35, least
